Billing numbers for different GST registered plants

we have 2 manufactiring plants, Plant A is in Bangalore & plant B is in Chennai. Both of the plants having different GST registered numbers.

we are using SAP, billing document is created. Both plants A&B having same number ranges for the billing documents.
Ex. plant A - 91
plant B - 92

These billing documents numbers has to upload in E-way bill portal.

My doubt is.

1. Can we maintain same billing numbe ranges for different GST registrations.

2. For E-way bill can we upload same number ranges for different GST registrations.
