Multiple substitution when repeating the previous command

I know that I can simply substitute a string with another in the previous command by typing:
!!:gs/string1/string2/
But how I can perform multiple substitutions, e.g. having a command:
echo "AAAAAAAAAAAAAAAAA" > test1
I want to substitute A with B and 1 with 2, so execute such a command:
echo "BBBBBBBBBBBBBBBBB" > test2
How can I do it with !! operator?
bash command-line history-expansion

$ echo "AAAAAAAAAAAAAAAAA" > test1
$ !!:gs/A/B/:s/1/2/
echo "BBBBBBBBBBBBBBBBB" > test2
That is, just add the second substitution to the end of the first. Just be aware that the second substitution will act on the result of the first.
