After thinking threw some compromises I wanted to share the template with you. It's not fully automatically and you have to do some work on your own, but I think it is not that bad considering that there is nothing like this here.
First of all you should know that you have to look up for a ServerPack.zip on your own. I can guarantee that this template works with the new modpacks (Not sure if it also works with older modpacks.). It will work if there are files like "FTBInstall.sh, ServerStart.sh and settings.sh"
If you want to edit the port you have to do this in the "server.propeties".
If you want to change starting parameters like the amount of RAM you can do this in the "settings.sh" config.
You can find the download links on the FTB Modpack site [Link in the server creation window], here you choose a pack, then go to "Files" and choose a version. Under "Additional Files" you can copy the link to the .zip archive.
I hope this helps a bit, have a lot of fun with my template.
Kind regards
