Load script to Objection on startup

I tried to use objection (Frida tool) and I want to load a JavaScript script in startup

I run it objection -g com.myapp explore but when I got prompt (to use import function` the application already running, that too late

So for know I use

frida  -U  -l myScript.js -f com.myapp
exit
frida-ps -Uai
objection -g PID explore 

Is there any way to use only objection to load script on startup ?
