How to restore multiple tmux sessions independently and simultaneously

[vkuznet]

I'm interested to know if it is possible to restore multiple tmux session started independently from scripts, e.g.
let's say I have to scripts

• file1 to start session bla and initialize some windows there

#!/bin/bash
tmux new-session -d -n abc -s bla
tmux neww      -t bla:2 -n xyz
tmux select-window -t bla:1
tmux -2 attach-session -t bla

• file2 to start session foo and initialize some windows there

#!/bin/bash
tmux new-session -d -n abc -s foo
tmux neww      -t foo:2 -n xyz
tmux select-window -t foo:1
tmux -2 attach-session -t foo

If I'll use set -g @continuum-restore 'on', then it will restore whatever I run latest. Is it possible to restore them individually after I re-run file1 and file2 such that session bla will be restored independetly from session foo.
