Is your feature request related to a problem? Please describe.
Automation in my Outlook setup means that I have event categories other than the default ones in Outlook

Describe the solution you'd like
On the Custom Colour Mapping screen instead of just a drop down of each default Outlook category, I would like to be able to add in my custom categories and map them to Google Calendar colours

Describe alternatives you've considered
I cannot think of another way to make this work

OGCS already picks up the categories, whether they are default or custom - though it may depends on how they are stored, as your screenshot seems to be from O365 Outlook on the Web?

Basically the categories that OGCS can use have to be in the Outlook Master Category List - can you provide more detail of the type of email account you have configured in Outlook and where the categories are defined? Lots of useful information here.
