Jira create - add option to assign directly

[Twi1ightSparkle]

Currently to create a Jira ticket and assign it to yourself (or someone else) you need two Hookshot commands, and they can't easily be chained since the 2nd needs the task number returned by the first.

!jira create Task "Testing Hokoshot" "This is a description" label1,test
!jira assign ABC-1234 twilight

It would be nice is there was an option on !jira create to assign immediately
