[5e] Second custom class

Morning everyone, I understand if you want a custom class you can click on the cog while editing a character sheet using the standard 5e template, and just above the section for custom classes there's another section for multiclassing (which prompts a drop-down menu with the PHB classes, not allowing for homebrew classes) But what if I wanted both at the same time ? ie - I'm already carrying one custom class, but am now hoping to multiclass into a second custom class. Is there a way to set this up, or does anybody know any workarounds? Much appreciated, Elizabeth

Just select one of the PHB options from the drop down and tick the multi-class box. Go to the core tab and change the CLASS & LEVEL display at the top so it reflects your custom class names. If you're using 2 custom classes, you have to do the entire sheet manually on level up anyway, none of the level+ multiclass functions will work, so all the second level is going to do is modify these Attributes: @{class_display}   -  this is just the text string that appears on the Core tab, as above @{hitdie_final}   -  a Query set up by the sheet for multiclass hit dice. The sheet doesn't even use it. No idea why tldr - the built in multiclass stuff is meaningless if you're going full homebrew as the Charactermancer doesn't work
