able to /gift more than 18stacks items​

Detailed description:

Hello,
Today I am here to give a suggestion about /maildelivery or /gift command. Currently you can only send 18 stacks of items to another player. My suggestion is to make it to 36 stacks which is a whole inventory. This could be a rank perk which increases the amount of stacks we could send to another player using the command or could be for everyone.​

Reason(s):

When you have to send a lot of items and not many shulkers, it is very annoying being only able to send 18stacks at a time.
I don't think it would cause any problem.
My friend wanted me to sell his pumpkins in blackmarket using rabbit pet, so he had to send 102 gifts for 56 inventories of pumpkins which could be reduced now.
It will conserve time.​
