PO Bill and Sub default auto populate fields from Supplier info or Settings

To help speed up PO, Bill and Subcontract entry if certain fields could be pre populated from supplier fields or system settings.

For a PO currently Issued By and Authorized By populates the same from the Prime Contract Contact. Would be useful to have system setting where you could have these populate based on settings from the logged in user, a project Internal Stakeholder Alias, the Prime Contract Contact or a specifically named User.

Most people we work with are always changing the issued by to the user creating the PO so would be good if could achieve this from settings.

Then for PO, Bill and Subcontract defaults could fields be added to supplier for default JCC and Resource. If the JCC matches a Project JCC then it will prepopulate.

For example you have a supplier that provides equipment hire which you would always code to an Equipment JCC and Resource L in PO and Bill. Or a company that does Subcontract Plumbing which would be coded to JCC Plumbing Resource S

Also there already is a default Tax code for a Supplier. Was hoping this could prepopulate into the default Tax code. Currently if leave blank then save it will fill in the tax code but it would be nice to have it populate so you can see it before saving. Also use same hierachy as current if supplier has no tax code then get from JCC default tax code.
