Yes.
If your emergency turn takes place at a set distance from a DME, or you are proceeding to a VOR/NDB or radial/distance to hold, then I am going to be putting that in the RadNav page. Especially if the SID doesn't require any hard tuning of navaids. Often the navaids auto-tuned in the box are not the ones you need for the EOSID.
Whilst it is in the secondary, and when the Bus loses an engine it should overlay the secondary onto your ND, I still would like raw data backup there ready. Just incase.
An EFATO, especially with a critical emergency turn is not the time to be relying on something with no redundancy because you've not set it up. (I've had in the sim in the past where the other guy has hit Delete Secondary instead of Activate Secondary. It wasn't a big deal because I was already following the raw data. It could have been a bigger deal if I hadn't though)
