Call a custom template in various places

[kh99]

You would need to use a plugin. In the plugin you'd set up any variables you need, register them to your template, then render the template and save the output in a variable. You'd then register that variable to the postbit template, and then use 'vb:raw' in postbit to put it where you want.

I know that sounds complicated, but it's not really that difficult. There's an article here on how to render a template: https://vborg.vbsupport.ru/showthread.php?t=228078
