Open Illustrator AI with spot colours in Designer

[prinector]

Hello,

when opening an Illustrator file in Designer, spot colours are not automatically displayed in the swatches.
Is there any other way / setting than manually selecting elements with spot colour and applying them via the context menu "Add to watches"?
This is the only way I have found so far to get the spot colours from the AI file to the swatches.

With the function "Create palette from document" colours are added, but they only have the name of the document (consecutively numbered).

Thanks in advance for any suggestions.

Kind regards
