[[Contracts] api doesn't support update "cis_registered" field.]

Hi,

Our project requests to handle 'cis_registered' field from api request

[Contracts] has "cis_registered" field. 
https://developer.sage.com/accounting/reference/contacts/#tag/Contacts/operation/postContacts

We can read 'cis_registered' field from api request.
But It's not support changing 'cis_registered' call by api(post/put) requests.

Can you support updating 'cis_registered' field by sage accounting api.

 

Sincerely,
