How to Change the Sequence Type?

When I want to create a sequence, there are several options, eg. ‘article’, ‘party’, etc. How can I change the sequence type if I figure that I eg. made a mistake?

I’m on Tryton 6.0.

AFAIK you are not able to modify the sequence type field through the user interface once it is already created, but you can deactivate or delete it and just create a new one.
Anyway, if you prefer it, you can just make an update to ir_sequence table and modify the sequence_type value but take care if this register is created by some xml file or if it’s already used.
