Prompt user before adding too many dynamic columns in Analysis Workspace

When utilizing freeform tables in Analysis Workspace, it's very easy to accidentally drag a dimension like "Day" into the column space when I meant to drag it in as a row. Depending on the setup, this can create many, many dynamic columns, to the point where data is no longer visible, Adobe slows while retrieving a large matrix of data, and Chrome slows to a grinding halt attempting to render everything. The only option at that point is to destroy the entire table and start over, since you can't even get your mouse in to click and select the columns to delete.

Could Workspace instead prompt the user if the number of columns created is over some reasonable amount (like 30) verifying that they are sure, before rendering the dynamic columns?
