Your question needs a better explanation.
You have a string of 197 lights and want 97 of them to be static and 100 of them to be sequenced?
If they aren't pixels you can't separate the control along the length of the string.
If they are pixels then an easy way to separate the control is to create 2 submodels. The first with the 97 and a second with 100. Put an on effect over the static ones and do whatever you want with the rest. You can also create a static and sequence group if you didn't want to have to go down to submodel level when sequencing.
