I wanna export one of my builds but I cant because it's on a template world

This is a separate post about this issue because the original I ran into is a couple years old and I want to bring more light to this topic:

I just spent a few hours on a build on a copy of my Realm using the Better On Bedrock add-on with the intention of copying it over using HoloPrint. Now I'm finding out that I can't even export a file because the structure blocks don't allow that on world templates! It's now discouraging me from using BOB on future worlds which is a shame because of how many great things it adds to the game. I haven't regretted my purchase since I got it but I definitely am a little now. And I'm definitely not going to buy any add-ons from now on because of this. So really Mojang just lost a marketplace customer because of this annoying little feature.
