Can a make a magical item that can only be used by a character of a certain level?

I was interested in introducing a few higher powered items into my homebrew game.

and was hoping to work out how to set requirements beyond strength/attunement/etc

Can DNDBeyond do this for homebrew items?

ie sword that require proficiency and class level 10 or higher?

Staff that can only be used by an arcane caster of 5th of higher level?

Scales that only give a benefit if you are proficient in deception

after all the hammer of thunderbolts- Giant bane property requires non standard "requirements"

Many of those things can be done simply by putting that information into the appropriate “Attunement Description” field. But it will be text, and not “enforceable” on the character sheet.
