2 views of same file with different show/hide conditional text

In 8 years, my FrameMaker "templates" for publishing display module datasheets have never remained static from one datasheet to the next. I always have changes that I need to carry forward to future publications -- ideas I glean from the technical support database; reviewer suggestions; different kinds of source information from our many suppliers; and from the constantly changing technology of the display industry.

In other words, I don't really have templates. Instead, I reuse my most recent publication for whatever "family" of display modules I am working on. I use conditional text to hide information when I publish a new datasheet. A few examples of the hidden information are "here is the formula to calculate the spec" and "use this X information only under these Y circumstances and keep hidden if not needed" or "have an engineer measure each time, then add 10% -- do not use supplier spec".

Example of final datasheet: http://www.crystalfontz.com/products/document/3187/CFA635-xxx-KL_Data_Sheet_Release_2013-03-06.pdf.)

I've tried keep how to/alternative information in separate files, but that adds too much time because of the nonstop changes. Ideally, I would like to open 2 views of a document at the same time: one with the hidden notes hidden and one with the hidden notes visible. This would make my work easier when I need make manual page breaks, be sure I applied conditional text to a paragraph return, etc.

Any thoughts on this? I am using FM10.
