Conditional Formatting And Inserting Row From Another Worksheet

To protect formulas and formatting, I have code, which copies a row, with formatting and formulas, from a hidden sheet, unprotect the main sheet, inserts the copied row and reprotect the main sheet. This works great, except with conditional formatting.

My current conditional formatting works on the range: $A$3:$B$100. The copied row is inserted on Row 4. When done, this splits the conditional formatting to: $A$3:$B$3 and $A$5:$B$101, whether or not the copied row contains the same conditional formatting. This makes sense, but is it possible to maintain the original, all-encompassing range? Otherwise I'll end up getting thousands of conditional formatting for each insert.
