can we add custom field in WSJF like Job size in place of story point , how it will calculate then WSJF value based on the value of job size .
when we install WSJF for JIRA , automaticaly it adds three field which calclulate cost of delay, duartion is taking from story point.
but what if i need to calculate WSJF for EPIC where i dn want to give storypoints and want to give job size as duration.
