Change assignment quick action Auto complete Rule in Redwood Page

We are trying to default the value of the Assignment Status to keep it as it is for a certain Action and Action Reason Combination in Change Assignment Redwood Page.

for example,

IF Action = 'A' and action reason = 'B' the assignment status should remain whatever it was before, meaning, if assignment status was "Active - Ben End" it should retain the value of "Active - Ben End". Currently we are not able to see option to get the current Value and retain it. Is there a way we can achieve it in VBCS?
