Skip buyer if requisition was automatically created into PO if the PO amount is within a certain lim

Hello Gurus,

We only use indirect procurement no inventory.

In our environment,requisitions are automatically created into PO.

Now for Requisition initiated change orders we want buyer intervention if the PO amount is greater than 50,000 USD otherwise no intervention is required.

Can this be achievable without any customization ??
