Support multiple simultaneous time shifts in the Interactive Table chart's Time Comparison

What is the problem or goal you're trying to solve or accomplish?

The customer wants a single table that compares a metric across several relative periods at once: current day, 1 day ago, 1 week ago, and 2 weeks ago, broken out by hour of day. This is a standard intraday pacing view (is today tracking ahead of or behind yesterday, last week, and two weeks ago at the same hour).

The Table chart already has a Time Comparison section with a Time shift control, but it accepts only one value. Selecting "1 day ago" produces one comparison column group (value, difference, percentage), with no way to add a second or third shift. The customer therefore cannot build the view in a single chart, and cannot compare more than two periods side by side.

Note this is not a request to add time comparison to the Table chart, which exists. It is specifically to make the Table chart's Time shift control accept multiple values, as the legacy time_compare control on Big Number and Time-series charts already does, and to render one column group per selected shift.

How are you solving it currently?

The customer built the table in Google Sheets instead, with one column per comparison period. In Preset they are limited to a single comparison per Table chart. Available workarounds inside Preset:

• Define one conditional-aggregation dataset metric per period (SUM(CASE WHEN <date> = <period> THEN <measure> END)) and place them all in a plain Table chart with time comparison off. Reproduces the layout but hard-codes the periods in SQL rather than deriving them from the dashboard time filter.

• Build a virtual dataset that self-joins or unions the shifted periods into separate columns.

• Place multiple single-shift Table charts side by side on the dashboard, which loses the shared row axis.

What is your recommended solution?

Make the Time shift control in the Table chart's Time Comparison section multi-select, matching the behavior of the equivalent control on Big Number and Time-series charts. For each selected shift, render its own column group under the metric, honoring the existing Comparison settings (value / difference / percentage) and the existing column-header naming so the periods remain distinguishable.
