Multiple Live Feed / Data

I have set an excel spreadsheet set up to update live data from a URL every 5 minutes. However I am wanting to do try and save a bit of time if possible.

Basically I am monitoring horses bought on a game website. Each horse has the same URL except for the number at the end which goes up in 1 increments. The URL is already set up and when the horse is bought it changes from being blank to having the horses details etc.

At the minute I am able to autofill cells with each uinique URL using fill, then series menu. This is so I dont have to manually enter each URL, as hundreds may be bought each day so it would take too long to do this.

My question is this, am i able to have a automatic series linked to the 'data from web' function in data tab, instead of having to manually adjusting each URL for each individual horse.
