GP - Draw - Thicknees profile (presest to save and select) vs Proportional Editing Object

In GP - Draw mode we can have custom Thicknees profile. But the problem is with "profile" as easy swith betwen some of this custom. This require to often modification around this profile to work with custom and remeber the curve chart for this. In Layer we have Proportional Editing Object as some of curve chart. My proposal is to:

• add this same feature as on Layer to Draw around Thicknees profile
• add option to save custom profile for select

Grease Pencil - Apply "Thickness Profile" to existing strokes - maybe after change curve chart on have custom Thicknees profil can be option "Save" and next "Apply" or something like this.
