Quick way of re-assigning classes of new symbols

[symo]

Hi All

 

Is there a quick way to re-assign the classes of newly-imported symbols? Im thinking that there might be a script that can do this - although its something Ive never done.

 

For symbols that I use often, I save them in a favourites file with everything re-classed. This gets a little tedious when I need to use a new type of truss at various lengths, and having to manually re-class everything. 

 

It is mostly truss and lighting symbols in Spotlight that I would like to re-class.

 

Do this in batches would save me a lot of time, if possible.

 

Cheers in advance.
