Ability to edit multiple elements in Remote Design

I’d like to see iOS Mail style editing for remote design buttons. I.E to select multiple buttons first and choose to delete or move.

In my setup I have about 90 Insteon devices controlled by ISY944. Using default Remote design for ISY944 pulls all 90 of control groups consisting of toggle button and Brightness slider, so total around 180. Creating a set of controls for each room took me a few days as I had to delete one by one controls not located in the given room. And again for each room.
Deletion currently takes two clicks each button. 1st click delete red dot on the left then click Delete slide out menu on the right. Very tiresome.
At least may be just slide out Delete menu, like in standard iOS interface would make it a bit faster. Also moving the group together around would be easier if could be selected together first.
