replicating an absence process with more vac types and absence chart

1

Hi there
the absence-wizard seems to be the only way to generate an absence-process in webcon.
the datasource for vact-types is seemingly hardcoded. I cannot change the dropdown, delete it, nor change the system connection to add more types.
if I add a new dropdown and simply hide the provided one, the data does not go where it´s supposed to go because it is not transparent where the data is written or how the absence-process figures out at what data to look.

if someone has replicated / self built a new absence-process with more vac types AND a absence-chart (calendar view) of colleagues, I would gladly know how.
thank you so much in advance
