Cigarette burn in roof pile

A 'guest' whilst travelling in the convertible marked the overscreen panel (above the front pillar) with a cigarette. Not a major hole, but unsightly nevertheless. Its the roof lining covered panel that holds the rear view mirror and light cluster.
(a) Can I obtain a replacement -havent seen one
or
(b) Can anyone recommend a fix ?
If it had been the pillar cover I have seen plenty of replacements, but isnt that just always the case.
