Desired end state: use a button to get it to the 
status, or at least to include all options, including Blank
I’ve seen:

https://connect.superhuman.com/t/set-control-value-to-a-list-that-includes-blank/35332
I think this used to work, but it doesn’t seem to work anymore:
[relation].SetControlValue(Table.ListCombine(''))
Here’s a doc demoing the bug
in relation settings - set the “starting value” to select all (including the blank), then use the ResetControlValue() formula
cheers!

Hi @Melanie_Teh! Thank you so much for the response!
This works for select lists
multi select list with select list set to all: ,A,B,New Add all [select 3].ResetControlValue()
But doesn’t work for multi select list that references a table, nor for relation types. Do you know of a way to do it with those?
trickyyyy, thank you!
Ah wait, hmm, no that doesn’t work. Seems that if it’s a Collaborative type select list then there’s no Starting value option:
Put “Table” in selectable items
