Items + Addons with Cheatengine?

Was there a way to add items or certain perks with HEX codes in cheat engine? let's put the bypass aside now, was there a way to do this and how so?

there was thread (closed now) "How to use known codes?" but considering hiromatsu post that hex codes were changed.. anyway you can try to change items to other ones.. there were also posts how to do such things.

uh this doesn't really help much, I already bypassed the CT, blood-points works fine, level changing works fine, not worth it if I can't add items or offerings because you can simply skip the work by just using a save, I've tried so hard to bypass because I simply knew there was something cool behind it that saves can't do, like having unlimited items for example or certain perks.
