@Phoenix_Fire absolutely there is! You absolutely do not have to do anything that you are not comfortable doing. The challenges are open to however you want to explore them 
So you could learn about anointing candles or dressing candles for a particular belief system or culture, how it may or may not be something you would practice, different ways to go about it, substitutions for doing so, safety concerns with dressing candles or considerations when doing so, alternative ways to incorporate them in practice.
Even if you don’t physically dress a candle 
you can explore anything to do with the practice & share what you learned about it. Whether it pertains to you or someone else or a group.
You could do meditation 
or the Interactive Virtual Altar or maybe try 
The Inner Temple for Casting Spells without Tools. It’s completely open to however you approach it in a way that’s comfortable for yourself & your practice.
