increment function: how can i start not from 1?

[rickopants]

Hi, i was wondering how can i use the --increment function but to also start from the 3rd character rather than 1 so i could give it for example 10 characters and tell it to use a mask but start from 3 and not from 1 like it usually does :

hashcat -m 0 --increment  hash1.txt  -a 3  ?a?a?a?a?a?a?a?a?a
it will do:
?a
?a?a
?a?a?a
?a?a?a?a
?a?a?a?a?a
?a?a?a?a?a?a
?a?a?a?a?a?a?a
?a?a?a?a?a?a?a?a
 ?a?a?a?a?a?a?a?a?a


where i want it to be like this:
?a?a?a
?a?a?a?a
?a?a?a?a?a
?a?a?a?a?a?a
?a?a?a?a?a?a?a
?a?a?a?a?a?a?a?a
 ?a?a?a?a?a?a?a?a?a



how can i achieve that?
