Current value for Batch Naming Series

Stock Settings provides a Naming series drop down for Batch, how to add more value to the dropdown?

Is there a way to set Current Value of Batch Naming Series?
If I want to start the Naming series from a particular number, is there a way to do it? I know we can do it for Doctype naming series from Naming Series doctype, could not find a way to do it for Batch
