Thank You, Under that same reasoning and the core rules pg 553...
"Adding New Abilities
Sometimes, lack of funds or time make it impossible for a
magic item crafter to create the desired item from scratch.
Fortunately, it is possible to enhance or build upon an existing
magic item. Only time, gold, and the various prerequisites
required of the new ability to be added to the magic item
restrict the type of additional powers one can place.
The cost to add additional abilities to an item is the same as
if the item was not magical, less the value of the original item.
Thus, a +1 longsword can be made into a +2 vorpal longsword,
with the cost to create it being equal to that of a +2 vorpal sword
minus the cost of a +1 longsword.
If the item is one that occupies a specific place on a
character’s body, the cost of adding any additional ability to
that item increases by 50%. For example, if a character adds
the power to confer invisibility to her ring of protection +2, the
cost of adding this ability is the same as for creating a ring of
invisibility multiplied by 1.5."
A player should be able to buy a +2 Belt of Str, then add a +2 Dex, then +2Con, and so forth paying the difference each time. This will also keep him completely within Core/Standard Magical Items.
I have been unable to locate where a ruling "official" was stipulated that a chronicle that gives access to a +4 glove of dexterity needs to be chaged to a standard item. It seems that all you need to do as a player is consider it a non-standard item. ex... the is a ring of sustanence in an adventure that takes up the bracer slot.
