Mass entry of entries during STO

Dear Experts,

I have a requirement where in the user has around 50-60 line items for which one STO needs to be created everytime. User does not want to do it manually by keying the material codes and quantity manually everytime since the material codes/quanitities may vary. Is there a way that we can directly pull the data from the excel in PO at one go instead of doing it manually.

Any help would be appreciated.

Thanks
