how to get component's variable in construct?

my AI have ‘PatrolRouteComponent’ and that Component have ‘Routes array variable’.

i want to draw arrow in construct for AI patrol route making, but can’t access Component, variables.

but when i use ‘Routes array variable in AIactor’, it works.

but i don’t like casting to Specific actor to access variables!

i like using ‘get components’. because it gives more flexible i think…
