yes it can mate,
Code:
<form action="http://www.yourcart.com/cart" method="post">
<input type="hidden" value="variable" />
<input type="hidden" value="variable" />
<input type="hidden" value="variable" />
<select name="itemname">
<option>x</option>
<option>y</option>
<option>z</option>
<option>w</option>
</select>
<input type="submit" value="Add to Basket" />
</form>
Now just add all your different variables in here and use the one submit to post it off... I know you can do this with RomanCart anyhow, that's what i'm experimenting with at the moment.
