Access current table filter in second formula?

I have a canvas button that is set up to modify a column in a table.

Is there any way to dynamically adjust the rows on which this button acts to match the current filter of the table?

Yes. If you use a canvas filter to filter the table, you can refer to the canvas filter by name, so that you can use that.

Alternatively, but not as dynamic, but helpful if you have multiple columns to filter, is to use the formula that Coda generated in the options area.

Come to think of it, you should be able to use that and include multiple canvas filters automatically.

In my phone now so cannot check.
