Summary Sheet Update Keeping Set Columns In Place

using code to take raw data from one workbook <book1> tab <Phase1RawData> and pasting to summary workbook <book2> onto <SummarySheet>. New data is available with each Phase (14 in all) and will eventually fill all cells as indicated in the Summary Sheet Page. However raw data has in any one Phase only the columns up to the Phase its currently at. So Phase 1 will only have Phase 1 column, Phase two will have columns for Phase 1 and 2, Phase 3 will have 1,2,3 and so on (the example Book1 has two example sheets for phase 1 and phase 2 data - so each phase has a column added with the previous columns remaining.)

The problem is in having the summary sheet always show all 14 phases colmns (as in the example attached) irrespective of which Phase is being updated. So if up to Phase 3, insert the raw data available will be colmns for Phase 1, 2 and 3 - but I need ensure after that has been updated only the remaining Phase colums to 14 show. That is, if Phase 1, 2 or 3 etc are now in place, insert the remaining blank Phase columns to, and including Phase 14. Need to do this at end of each phase until 14 is met. The data up to column S is all from the raw data original sheet - Items from Column T I insert independantly as the data is transferred.
