Massive Upload Agreement Quantities

Hello,

Is there a way in Management Agreement, after creating a new contract/agreement to enter more than 500 lines in Agreement Quantities P38011.

Can we upload Agreement Quantities through excel?

Would it work if create the agreement in Agreement Master, take the row exit to go to Agreement Quantities and upload data through "Import Grid Data" Functionality?

User also needs to add the Agreement Source/Destination by taking the row exit from Agreement Quantities. Is it possible to have the Transaction Source, Type, and quantity uploaded all at once?

(Otherwise the user has to go to each Agreement Quantities, take row exit to Agreement Source/Destination, and manually enter data for more than 500 times).
