Thanks for the suggestion. I've found a plugin that should be able to do
this, now I just need to find some time to include it with Tiled and
test if it works. I've opened this issue about it for when I get around
to this:
https://github.com/bjorn/tiled/issues/708
Subscribe or comment there if you want to get notified about this. I
don't know when I'll get around to it, so any others interested in this
should feel invited to take on this issue as well!
Cheers,
Bjørn
