Structureblock save to memory / file configurability (redstone) java

It would be very usefull if structureblocks came with a configurable option to save the structure to file instead of memory when triggerd by redstone. as there is currently no way to ''automaticly'' save structures to the file. this would create a bunch of options for mapmakers.

this could best be done if its in the GUI of the structureblock. and is standart on what it is now ( handsave > file, redstone save > memory)  but that u can change it so that (redstone save > file). if this is not possible then perhaps via a gamerule. just having the option would be fantastic.
