Change weapon damage with procedures

HI,

i wanted to ask if someone knows if i can change the damage that is shown on an item through prodecures?

Like for example Sharpness changes the damage of a diamond sword from 7 Attack Damage to 10 Attack Damage.

I know that i can use the "deal (number) damage to (entity)" to technically do more damage but it would be nice to actually have it visually represented on my weapon.

Thanks in advance.
