Feature Request - Add bonuses field to the new check feature

[4m2c4bl3]

There are a few abilities in FU that apply specific bonuses to various checks.
Example from Orator:

In the base game, Focused gives a bonus of SL to checks done with it using INS + INS.
"When you perform an Open Check using 【INS + INS】, you gain a bonus equal to 【SL】 on that Check (this only applies to Open Checks)."

In the playtest material, Condemn functions as an opposed check, with a bonus to that check based on your SL.
"You gain a bonus equal to 【SL】 to your 【INS + WLP】 Checks for this Skill."

I'd love to be able to create easy rolls for my players using the new inline check tool done by @Azurelol. Right now they tend to just hit the dice button on their sheet, and then say out loud any bonuses they have to that.
For me to be able to implement this, the check tool would need an extra field in it for skill level bonuses. It makes the most sense to me to simply have an additional field where you can input a flat number bonus, and/or the new inline expressions.

Perhaps something like @CHECK[val1 val2 (bonusValues) optionalDL] ? This way the regex parser can take everything inside () to apply as the bonus, and we can use things like $sl*10, without worrying about spaces between the values, etc.
