We're looking into creating an action that is composed of other actions in YAML but can't find anything on that. Is this supported or going to be supported in the future?
I opened forum to ask the very same question myself :)
Indeed, as the community grows it should be possible to create more or less complex actions by simply combining other actions with 0 coding. Very interesting feature.
Bump on this for me as well. When creating cross platform worflows I end up having to create several nearly identical jobs. This is frustrating because it requires a lot of repeating myself. If I could create actions by composing several smaller actions and providing inputs, I'd be able to drastically reduce the amount of boilerplate I'm using.
