Add setting to specify next increment Id increase from 1 to specific number?

I would like to control the next increment Id generated by data migration tool. The current setup works well, but I have a project that requires a gap between M1 and M2 increment Ids, as the original M1 will continue to process some orders.

Preconditions

1. Magento 1.14.4.0
2. Magento 2.3.0
3. PHP 7.2.16
4. MySQL 5.7.25

Steps to reproduce

1. Convert data from Magento 1 to Magento 2
2. Next increment Id is last increment on Magento PLUS 1

e.g. in M1: 308774316 in M2: 308774317

Expected result

1. Add setting to allow next increment to be: last increment + config setting in settings.xml (e.g. 1, or any number of choosing).

e.g. in M1: 308774316 in M2: 308874316 (using setting of 100000)

Actual result

1. 308774317
