Quicken Spell-Like Ability feat says
Using a quickened spell-like ability is a swift action...
In addition, a spell-like ability that duplicates a spell with a casting time greater than 1 full round cannot be quickened.
However there are spell-like abilities that do not copy any spells but take multiple rounds like Alternate Form. In the case of a spell-like ability not duplicating a spell but taking multiple rounds can the spell-like ability be quickened?
