Milestones: Handle multiple milestones through the name

[Seraf]

Hello,

I'm currently having in my board a column per milestone, like Q2 2020, Q3 2020 etc. I'd like to map them to their respective milestone name.

I added a card on those columns:

###### Automation Rules

- `milestoned_issue` **Q3 2020**

But when I assign an issue to Q2, it goes first to the Q2 column, THEN to Q3 column. I think that the milestoned attribute doesn't read the payload to extract the name, it could be great to have this filtering to have more granular rules.

Thanks for your app, that's really awesome :)
