Trick to setting up temple?

Hey there, new to PoE2 but long-time veteran of poe1 who enjoys more complicated mechanics, therefore I got curious when I read upon the Temple mechanics in PoE2. Last league I only finished Arbiter questline so this is the first league I try to grasp farming concepts, a bit of crafting and atlas, so please keep this in mind if my questions are stupid 😄

I tried to set up a temple farm following Ronarrays and GhazzyTVs videos explaining how to approach Atziri rush while utilizing a bit of temple building but I am lost at multiple points:

1. 4 times now I had to open a temple while trying to get the right puzzle pieces to path to atziri, everytime I got closer the temple deleted the last "streets" while destabilizing. Is there a Trick so the pathways stay longer? Starts to be very frustrating farming 24 maps with barely any proression.

2. Naturally I was playing around early so my layout at the top is pretty screwed. Is there a way to "hard reset" the temple or do I have to correct it from time to time, using destabilization to hopefully delete wrong parts?

3. I ran into the problem that I get always the wrong street-parts. Just to be sure: There is no way to turn them 90 or 180 degrees, right?

4. Following 3: do I actually have to ALWAYS spend all 6 puzzle pieces? Sometimes when the pathway parts lead in the wrong direction I kinda see no reason to actually use them. Does this have some negative effect?

If you have any further tipps I would also love to hear it! Thx
