I know it's possible to increase value of autonumber like this
`autonumber inc B`
however if I have some logic like if branches, I'd like to increase the indent. So for example if numbering goes 1,2,3 and now I have branch I'd like to have 3.1, 3.2 .... and then go back to 4. Is this somehow possible without specifying hardcode value like `autonumber 3.1`?
