Start Animation with click on multiple trigger (after one another)

[KaySunset]

Hello,
after spending half a day trying, I'm giving up and try to find help here I would like to depict animated lanes from Asia to the US. The layout is as follows:
A map of Asia on the left, a map of the USA on the right side. Above this, there are different texts stating the origins (e.g."Bangkok", "Singapore") and the destinations ("Miami", "Atlanta",...)


In between those two graphics I'd like to let arrows appear that go from Bangkok to Miami, BAngkok to Atlanta,... according to the origin and destination that I clicked on - one after another (because otherwise I would have to write out all different combinations, what would not look very nice). In case that is easier to do it would also be okay if there was a hyperlink to another slide that opens only after clicking on two different objects.
As I am not familiar with VBA, it would be nice to have a solution without it - but if there is only a VBA solution I'd still be happy to have it, I'm confident that I might actually be able to do it

And just in case somebody really wants to hit it: Maybe there would even be a possibility that one could choose out of a dropdown list, after choosing two different things the arrow/a new page pops up.

Thanks a lot for the help and please excuse my English, I am not a native speaker.
