Is it possible to save text filters?

[rsharman]

I'm using Scribus 1.6.1 on a Mac.  I'm trying to convert a document from Swift Publisher.  I've extracted the text and gone through several iterations of text filters and new styles.  When I went to re-import today and use filter4 all the "apply", "Paragraph style", "starting with" and so on things in the filter were there but the actual paragraph styles to use were all empty!  I have an earlier filter3 but a lot has changed since then.
1. Any idea why I somehow lost the paragraph styles to replace?
2. Is there any way of saving these filters?  This would help preventing losses, bad changes, and possibly would make them easier to generate.
Thanks, Richard

I'm a little lost by what you mean by "text filters", some details please.
And when you say you "re-imported" what do you mean by this?  did you import the same text? as in replacing what you had imported previously? or is this new text? and is it being added to  the previous import? or is it replacing it?
