About use :ingreso_or_multiples_retiros instead of :ingreso_or or add it

[cavi21]

Hi there, I was wondering if you have any preference on how to implement this other call :ingreso_or_multiples_retiros, Maybe replace the existing one? or add it?

Also FYI the actual create_pickup_order doesn't allow to create a SAP service (Sucursal a Puerta) and we need that to drop packages on different stores and not only to request a pickup by using idcentroimposicionorigen.

The : ingreso_or_multiples_retiros have another XML structure also and properly allows to create those type of "Shipment Orders".

I imagine that you are currently using the actual implementation, so maybe add this other feature maybe make sense? what do you think? Happy to open a PR and discuss it all the way if you are OK with that.

PS: Also I wrote in english based on previous issues and PRs that I saw here but also if you prefer to discuss them in spanish I ok with that too.
