Can a Seeker take up multiple grid spots?

Is it possible in a hexagon grid system to have units that take up more than 1 spot on the grid? If so, what is the exact setup for the seeker to be able to handle this?

Note: I’ve seen a few questions to this already, but they are all quite old and I was wondering if there is an updated solution for this that you recommend.

Currently this is not possible I’m afraid.
It is possible with a custom ITraversalProvider (which the hexagon example scene uses behind the scenes), but it is not an out of the box solution. I could help you write one if this is necessary for your game though.
