TL;DR

1) Add an option to avoid upgrade planner to edit the original blueprint.
2 Allow to apply a temporary upgrade planner rather than a predefined one

What?

1) When applying an upgrade planner to a blueprint, make it possible to save the result as a copy rather than editing the original blueprint.
It could even be the default option, you get the result as a copy on your cursor and it's up to you to save it in your book or just keeping it in your inventory as a disposable variant of your original.

2) Currently you need to have a predefined upgrade planner to apply it on a blueprint.
Proposal is to be able to defined a new temporary upgrade planner where you can setup the changes just for this time.

Why?

Both suggestion comes from the same finding in space age :
With the variety of module and building quality, the number of possible variations of a given blueprint is endless.
While you progress through the game, you may not have all quality modules/building at your disposal (especially with the different planets)
The "one fits all" approach for blueprint is not true anymore in space age (except maybe endgame when you have all legendary items at hand).
Same goes for upgrade planner, it's tedious to maintain one for each situation (depending on the planet, quality at your disposition, etc)

These improvements would complement greatly the parameterized blueprint feature and act as a kind of "building/module parameterization" capability.
