Manually Enter DOGE and LITECOIN

I have a robinhood account and I am manually entering everything into Quicken. I found simple entries for Bitcoin (INDEX:NQBT0 and Ether (INDEX:NQETH). But I can't find similar entries for DOGE or LITECOIN. Can someone else help with this? I did notice a PDF posted on another discussion but it had multiple entries like LTE5, LTE10, LTE25, etc. and I don't know what each one of those stands for and what the difference is.
Can someone let me know what they use?

Also, is there an ETA with quicken to better support this? Now that they are a subscription model and making us pay yearly, I would hope they do more to keep up with current accounts and crypto.

Thank you in advance.
