Customize highlight colors

It would be a nice feature if in LibreWriter you could customize highlight custom colors not every time anew, but one time for ever.
So far it seems impossible, isn’t it?
Thanks

Not sure about I get you right - but you can create your own palette using your custom colors for highlighting (see Farbpalette erstellen - The Document Foundation Wiki)

very good! It’s what I was searching for! Thank you very much!

For the record(s) - according to OP’s comment:
