How to create/edit TTC file Font?

Hi everyone,
Is there way to edit a TTC file font? I have a TTC file, i want to extract (this could use Extract from TTC in Fontcreator), then editing the TTF files inside, how to build again the TTC file for using?

Thanks 4 helping,

FontCreator can extract TTC fonts to edit the individual Truetype Fonts, but you will have to look for other tools to rebuild the TTC font file.
