how do i enter multiple stock sales for a single 1099-b when the number of shares exceed TT limit

I received a single 1099-B from my employer that shows the total proceeds for multiple ISO stock I sold. This is from multiple lots acquired over several years and they are all different sales as the basis and gain are different for each.
In TurboTax (Premiere) when I say I got a 1099-B then it tries to use the TOTAL (from the 1099-B line 1d "proceeds") for EACH sale I enter.  When I walk thru each sale then I get to "Enter Your Sales Information" page it limits the number of shares and I have more than the 99,999 it allows. So my total number of shares is larger than TT will allow and then won’t match my 1099-B
I have used TT each of the years and tracked via the ISO step thru model so the data is there and AMT impacts. Looks like I have to re-enter that data but then I run into the max share problem.
Any thoughts or help would be appreciated.
