signing of Lodgement Instructions - Responsible Subscriber - subscriber hasn't created document
Is there any way in a non-transfer workspace, to change the responsible subscriber of the lodgement instructions to be a subscriber which is not a signatory to any documents created in the workspace. For example, a financial settlement whereby a caveator on title is lodging a withdrawal of caveat and being paid a sum of money by the proprietor on title (which is also a participant / subscriber in workspace). Because the responsible subscriber is only providing the source funds, they only authorise and sign the financial statement and not the lodging instructions, because the proprietor on title has not created any documents. Given that the payment of funds is conditional upon the withdrawals of caveats being lodged, shouldn't the proprietor on title be the responsible lodging party and sign the lodgement instructions?
