[REQUEST] Add command parameter

[DevTimur]

Hi, you got command

/reskillable incrementskill @p reskillable.agility

And it's increasing certain skill by 1.
Can you please make so if you NOT select amount of levels it add only 1, but if you DO select it add amount of levels you select
Example

/reskillable incrementskill @p reskillable.agility 3

will add 3 to that skill

Main reason why i ask it.
I got modpack where you get skill points for advancments, i use command to increase skill level, but when i need to increase it multiple levels i forced to run command couple times, and each time it give toast notification. Basically it's filling top right corner of screens. I want to avoid that filling. only one toast popup will be much better. ty.
