Add multi-select functionality for alert stages

[mclean25]

It would be super handy to have multi-select toggle on the stages for a given alert. We have ~25 (and growing) stages and it would be super painful to set up these alerts each for all of them. Selecting all doesn't work for our use case as there's ~1-2 that we want to treat differently.

Are these stages for the same app btw?

Right now the workaround would be to duplicate this rule for those stages. Another alternative I can see is having a "select all stages" rule and rule (or two) for those stages that are the exception.

They are for the same app, yes.

I see, so there's a hierarchal rule implicit here where alerts for a given stage will override alerts set to all stages? That would certainly make what we want done easy.

Something that might be easier to implement is account based rules for alerts. ie: alerts configured for all stages for a given AWS account.

It won't override from what I recall. I think for those stages you'll sadly get alerts from both the rules.

The AWS account is a nice idea. I'll share it internally.
