Have a read at my thoughts on understanding this concept here
You have the ability to p-lock and set trigs and anything you might like to do in ‘regular’ grid mode directly from the Euclidean mode - think of the Euclidean mode as a different way to view the same content.
What you are describing works in reverse, if you have p-locks on the sequence before hand, then those settings or TRCs or whatever will be translated directly to the way the euclidean pattern is heard.
They are seamlessly connected, there’s a 1:1 connect to the pattern ‘beneath’ which i try to describe in that link
