Way to run a lua function after all packages are loaded

[no-more-secrets]

After much searching, packer.nvim doesn't seem to have any way to hook into the loading process that runs each time nvim starts. Basically, I just want a simple way to load all of the lua modules that configure my plugins, but to do so after all plugins are finished loading. I am aware of the config = options, but I have to specify that manually for each plugin. Also I am aware of the PackerComplete user command, but that doesn't seem to run when nvim just starts up normally.
