So if I build a set of inputs and save them as a preset named "Show-001".
Then I build a new set of inputs and save them as a preset named "Show-002".
So now preset "Show-002" is the current preset that is open.
Now say I want to add a few of the input from "Show-001" to the current preset that is open "Show-002".
So I select OPEN the select preset "Show-001"
I select from the list of the inputs in "Show-001" and choose APPEND.
All good so far.
The problem is now that I have "Show-002" setup just the way I want it,
if I now save the preset it defaults to the appended preset name which is "Show-001"
which then obviously over writes my existing "Show-001".

My suggestion is:
If you APPEND to an open preset it keeps the original open set name.
If you OPEN a preset it then obviously uses the preset you opened as the name to save as.

For example:
If open preset "Show-001" then APPEND a few input from preset "Show-002"
The save as name should stay "Show-001"

Make sense?

I have also problem with this. Always have to rename to the old name.
Very easy to do wrong with it as it is now.
