create single role copy of composite role in sap security

We have a composite role Z_RUC_ALL_FICO_PAAKAYTTAJA. It includes dozens of single roles ( Approx: 30 single roles).

We would need to create a new single role which includes all transactions and authorizations from composite Z_RUC_ALL_FICO_PAAKAYTTAJA and some added transactions. Is it possible to merge those single roles in FICO_PAAKAYTTAJA to one new single role? Any best procdure ?

Need to copy all data of 30 single roles into new one single role at one shot to avoid manually work

My option is: Yes possiblity is there

first download all tcode,auth object values,Org values from AGR tables and create one single role and add all these Tcodes,org values etc

Or Create single roles and insert all profiles fo all single roles and maintain Auth data manually by refering AGR tables data.
