Can you pass data/variables between alert conditions?

Anyone know if this is possible to pass data/variables between conditions whether they be alert conditions or trigger conditions? That would be useful if you needed to formulate something and massage some data then use it in the next condition/step...

You can use a subquery in the custom SWQL bit to do what you describe, can be a bit fiddily to work with.

Your use case sounds like you're trying to get alerting levels into the product, i think, I've not seen anyone do this without getting another tool involved. Seems possible, though will make your alert fairly hard to understand for a newbie, recommend adding a lot of comments.

I think in practice you'd want to select from the layer you eventually care about (nodes here), then specifically right or left join a subquery to white/blacklist the stuff you do/dont care about
