I am an attorney doing multiple practice areas (such as bankruptcy, criminal, family). 

I can create a layout for each of the practice areas but doing so does not increase the amount of fields that I have available.  What is a workaround to this?  With each practice area, I can make use of the maximum number of fields.  In other words, if the maximum number of fields is 100, I could make use of 100 fields for each practice area.
