Easiest way to create lich, ghoul or ghost

[MarcelGM]

Hey all,
the Bestiary has these ability/trait adjustments to turn a creature into an lich, ghost and some other undead using what used to be considered a PF1 Template

What is the easiest way of doing this in HLO? I dont think all ability adjustments exist as a templated thing that can be dropped onto an NPC right?

is the path to get to Lich for example to create an wizard and then go into Customize>Permanent Adjustments and start putting together the abilities and traits specified under the monster entry in the Bestiary?

first time attempting this, thanks
