It is possible to work around the limits of the scoping tbh by triggering an event sequence. I have some code for CKII, that simulates the two party diplomatic interactions by scoping to all valid characters and letting each display of character options leave a tag on the characters. This can be done in Stellaris with scopes to planets, fleets or leaders using flags to assign a yes/no check and then having a final event option to give more options. While it is undoubtedly annoying to do, it is possible.
It would even work substantially better for Stellaris, because it does not have the limit of four event options so is able to display far more information on each individual page.
