Yes, of course, on the wiki this will (easily) be possible via a template, e.g.
{{formula | ogf= ... | egf= ... | rec = ... | direct=... }}
once again, either authors respect this formatting directive,
or we can write a bot scanning for "improperly edited" sequences
(e.g. where the fromula is given as
===Formula===
* a(n) = ..
* o.g.f. = ...
etc)
and doing the necessary changes automatically or semi-automatically.
