How to create step template as combination of 2 existing step templates?

I want to create a step template that will deploy a package and create a scheduled task that will run exe from the installed package.
I can do them as two separate steps (the second using https://library.octopusdeploy.com/step-template/actiontemplate-windows-scheduled-task-create).
But I wish to have it as one step to be added to a few similar deployment projects.
How it can be done?
I am new to Octopus projects, sorry, if I missed something obvious.

I think, I found the answer- it is one of highly voted feature requests -https://octopusdeploy.uservoice.com/forums/170787-general/suggestions/12948603-composite-step-templates#comments

Hi Michael,

Thanks for reaching out. You are correct, this is currently not possible in Octopus, and the correct next step would be to vote for that feature.

You could also create the step template based on the “Deploy a package” step, and then add the logic to create the scheduled task as a Post-Deployment script.

Best regards,
