If you create your price list in Excel you should be able to link it to your artistic looking price list such that when you update your prices it changes your main one automatically otherwise you have to do it manually.
You do it by inserting an object but I have forgotten how to do it as its a long time since I had to do such things
Just had a quick mental refresh, you copy the item from the Excel spreadsheet and then "paste special" into your target doc but make sure you paste the link and then if you change the source doc , the spreadsheet the target doc updates automatically
