This is not documented and exactly what you are looking for, but you can have:

@startuml
autonumber 1.1.1
Alice -> Bob: Authentication request
Bob --> Alice: Response

autonumber inc B
'Now we have 1.2.1
Dave -> Foobar: TestA
Foobar --> Dave: Another testB

autonumber inc A
'Now we have 2.1.1
Dave -> Foobar: TestC
Foobar --> Dave: Another testD

autonumber inc B
'Now we have 2.2.1
Dave -> Foobar: TestE
Foobar --> Dave: Another testF

is there any way that  'autonumber' keywords works with 'activate' keywords and  detects differenct  layout automatically
