The developer has created a bot that combines stickers from different sets into one.
“Your stickers” is the name of the bot that collects the stickers from different sets into one. You can gather a small collection of my favorite stickers, and delete unwanted sets. Bot works just need to send stickers, and in return you will receive a link to your personal set.
If you want to sort or remove the stickers, you need to send the desired sticker from the personal set and choose one of the options.
