Set SLA based on card priority

Is it possibile to set SLA for a card in an specific step of the flow based on a custom priority field?

Here is my scenario:

I have a custom “select from list” field labeld “priority” which accepts values from 1 to 5 (such that 1 indicates the highest priority and 5 the lowest). I would like to set a shorter SLA when priority is higher.

I could create 5 different columns, one for each priority level, but that would make the pipe confusing.
