More fonts please

Hello from a newbie to Zoho Writer. I would be deeply and almost eternally grateful if someone would make it possible to upload whatever TrueType or OpenType fonts I want to use. I have about 8 fonts that I usually use for my documents which are not very commonly used, and which seem to be mostly unavailable in Zoho Writer. Am I wrong about that? Any help or advice will be appreciated. Michael: mdcai.mlm@gmail.com
