Aspose.Slides Product Family

Hi Team,

We are planning to buy this product for our organization. So currently I am testing your product with temporary license for this product.
We are using this product to merge different PPT files into single file.
For that I create one Master default slide which have page number. So while we merge different ppt we have unique number on each slide which we want.

But, main issue is if any of our selection ppt file using any type of master inside that than it will cause an issue while we merge with our new ppt file. Mainly we loss all formatting while clone source slide to destination.

So we want page number in new merge file and want to keep same source formatting to destination slide. So, need solution for that as soon as possible.
Please see attachment files for that with issue sample file and test file along with master file.
