First, just to clear up - Interchange does not save these values
into cookies.  Interchange uses one cookie to save your session ID.
The session information is stored and handled by Interchange.
If a user switches cookie usage off in their browser then another
technique is used to pass the session ID around.

You can modify the following as you see fit:  To save a text value
along with a cart item, you can add the following to your "add to cart"
form on your flypage:

    <input type="hidden" name="mv_item_option" value="itemtext">
    <input type="text" name="mv_order_itemtext" value="" size="20">

You can retrieve this information on your cart and checkout pages,
or wherever, using a tag such as [item-modifier itemtext].  Change
the "itemtext" identifier to anything you like, but use the same
identifier in the "mv_item_option" value, the "mv_order_" name and
the [item-modifier] tag parameter.

Repeat those two lines for every one of the item's options, but change
the "itemtext" identifier.

You may also find the AutoModifier directive useful.
