Batch apply font to layers of different canvases

I’m giving OG7 a spin.

I recently updated to Mac os Sierra and upon opening a OG6 document, the OS is asking me to download a Chinese font again I used for that OG6 document. OG7 reverted all the text in that font to a system font one.

Now I want to apply back the original font. I’m talking about a single document having about 30 canvases and each canvas having different text layers, one of them being in Chinese. I don’t want to manually select each text layer in each canvas using that Chinese font. Is there a way to automate this process ?
