Dear @Vytenis,
As you can see I added a date column from when the “value” will be available and an “available column” with the following formula If(Avail_Date<=Today(),true,false).
Then create a view of the “select value” table, where you filter Available=true
IMPORTANT: select the “view of Select values” table to choose from!
This should be the first step towards implementing this user case.
Special thanks to @Ander, building the formulas 
Unfortunattely I can not assign more time for the moment, but for sure I will do my best to support on the development of this interesting user case 
Kind regards,
