DropDown in RTC

In the table designer the fields that appear in the drop down list are defined.  For example the Customer table.

I found a feedback in Microsoft Connect and added a few comments to that.  What I would like the drop down window to be able to do is;

• remember the last position and default to that one
• allow multi select that will result in a filter

I would love this to be applied to both pages and the report “Show results:” area.
