In conference situations , we can have a large led wall with a background and many PIPs that change position and size many many times during the show. If we need to do size and mapping positions for each column (even when coping the values) its taking a very long time to program .

to have simple way of creating mapping positions which can be easily triggered regardless of the content its showing.

I managed to do so using 2 instances of millumin , but its not really convenient as it can only be triggered using midi controller or something
