Cannot customize range on a touch device

I've a Microsoft surface and want to reduce the profile to a given range (start and end point). By touching I can set the marker appropriately but it's not possible to actually slide this marker to select a range. Possibly a touch hold long enough and sliding away should probably put the UI into the range selection mode.
