It appears that there are no existing settings or configurations that would allow Customer\Vendor transactions to post 'Through' the General Ledger by default.
Typically, if a module lacks specific setups for this purpose, the next place to check would be under the general posting settings (Tools>Setup>Posting>Posting). However, upon examination, there are no particular setups for Customer/Vendor Consolidation in this section either.
