Evergreen rule to respect current event days

I want to make a 4 day event Evergreen and keep the current timings. I want to repeat the event every 1 month, starting on the first Monday of the month. Using the wonderful new “select all feature” works for day 1 of the event, but the other days all end up on day 1 too because they are all being placed on the first Monday of the next month. Can we add a toggle to somehow respect the current days (separation)?

I can’t workaround this by selecting each day and programming the Evergreen settings 4 times because for example, in Jan, my day 4 would start before my day 1 (first Thursday in Jan is before the first Monday).

Also, please know that the fast forward button mouseover guidance (manually update to next) defaults to UK time.
