Is there a way to view known blueprints without an empty upgrade slot?

Consider the Multi-tool. I randomly encountered an Alien who gave me a very good multi-tool with very strong lasers and stuff. All I had to add was the scanner and I was good to go.

However, after a while, I began wondering if it was worth deconstructing some of the upgrades in case I know a higher-tier blueprint. But I am not certain about which blueprints I know. As far as I'm aware, the only way to view the list of my known multi-tool blueprints is to deconstruct one slot and try to craft something new in it. But this seems wasteful. Is there not a way to view the list of known blueprints otherwise?

Not for the multi-tool (on PS4).

All products that can be constructed in the suit can also be constructed in the ship, so if you have no free slot in one you can at least check product blueprints in the other. (Not so for upgrades, of course.)

On the plus (?) side, enhancement blueprints seem to be pretty limited (at least as far as I am into the game) so if you get only duplicate suit, ship, and multi-tool blueprints 100 times in row, it's a good bet you've found everything.

Of course that still doesn't help if you're just trying to check the ingredient list for an upgrade, which is where the internets come in. :)

Go to the guide screen (between options and log) and select Technology.... if I'm remembering correctly, the blueprints you have will have a wrench icon in the lower right corner
