How can we use a custom filter and standard filters on the same image?

[FahadSaleem]

I am currently using a group of filters using val mCurrentConfig = "@adjust brightness 0 @adjust contrast 1 @adjust saturation 1 #unpack @blur lerp 0 @adjust sharpen 0 @adjust exposure 0"

I want to add a custom filter to this group as well (vibrance filter). Can anyone tell me how I can add it in the same group as these standard filters so the final result is a combination of all these filters? (mCurrentConfig + vibrance custom)
