Include Peers/seeders From Old Torrent In New Torrent

[WhiteFang]

A year ago I created a torrent with about 100 files.

 

Now a year later I want to create a new torrent wich includes the 100 files from the previous torrent and about 50 new files. All these files are on my computer, but the old torrent has a lot of peers and seeders and I like to include those peers/seeds for the 100 files wich many people already have downloaded.

 

I already found a option called "Similair Torrents" wich seems wat I need but I cannot find an explanation about it (don't know what to put in there). (see arrow in included image)

 

 

Maybe someone can help me out?

 

Tanks in advance, WhiteFang
