Feature request: Expose user fields on purchase workflow parameters

I have been told that ApprovalMax are ending support for their CIN7 Core integration in August 2025 so I was advised that purchase workflows in CIN7 Core may be an alternative solution. However currently user data is unavailable as a parameter in a purchase workflow in CIN7 Core. It would be great if it was possible to route purchase approvals by specific users to certain people, for example their manager for approval. 

My only workaround at present is asking staff to enter their name in the Notes and filtering on that, however that doesn't allow for human error (typos and upper/lower case case etc.), so filtering on the user would be ideal. Alternatively, filtering on membership of an email list would also work well if easier to implement? E.g. if email address of user in list do X.
