Bash Module - sourcing files in module_utils

I have a bash module in plugins/modules

# my_module.sh
function do_something1() {

...
}

source ../module_utils/my_other_source.sh

do_something1
do_something2

source file in plugins/module_utils

# my_other_source.sh
function do_something2() {
...
}

Only Python/powershell has that type of feature. There is no support for module_utils with a bash module.
