Conga symbols request

Hi all

First of all i would like to say thanks for such a good notation software.

The only things i miss are the note symbols for the basic conga hits(heel, toe, bass, open, muffled, slap) which are essential for writing conga sheet even for the most simple rhythms such as calypso or cumbia.
Although the symbol standards are not yet specified, all of the conga sheet i met are the same in the symbol of
open tone(basic note symbol) and the
slap (a symbol of 'x' same as some percussion notes).
The heel is usually noted with a triangle downwards or ///in the case of some traditional cuban lessons in which the heel is played always as a bass/// is the same as the bass tone (empty circle).
The toe or tip is usually symbolized with a triangle upwards or a half-circle upwards( like letter 'C' turned 90 degrees right).
The muffled stroke is usually a horizontal thickened line (like _ ) in some cases i saw it as an angled symbol turned 30-45 degrees left.

I've met another form of conga notation in which the types of strokes were written under the notation line like RB-right bass, LS- left slap, etc.

Thank you and have a nice day :)
