Substitute blueberries with jam?

[Dg21]

There is this recipe that calls for fresh blueberries but unfortunately accessibility to blueberries in my country are limited and otherwise very expensive! I really want to try out this recipe however, can I use blueberry jam instead? And in return reduce the amount of sugar?
These are the ingredients for this recipe:


Lemon Blueberry Yogurt Cake
Ingredients:
[ ] 3/4 cup milk of choice
[ ] 1/4 cup lemon juice
[ ] 1/2 cup plain yogurt (115g)
[ ] 1 tbsp ground flax (5g)
[ ] 1 1/2 tbsp lemon zest (important)
[ ] 1 tsp pure vanilla extract (6g)
[ ] 3 tbsp coconut or veg oil (30g)
----------------------------------
[ ] 2 cups spelt flour, all-purpose, or Bob’s gf (250g)
[ ] 2/3 cups xylitol or sugar (or sucanat) (130g)
[ ] 4 tsp baking powder
[ ] 1 tsp salt
[ ] 1/16 tsp pure stevia, or 2 extra tbsp sugar (or 2 NuNaturals packets)
[ ] 1 cup blueberries (140g)
----------------------------------
[ ] 1/3 cup more blueberries (50g)

can anyone help me out? Is this feasible in any way? If yes, how much should I use as a substitute?
TIA

If the fruit is cooked down and made into a jam, then added between the layers as a filling, the you can use jam as a substitute.

If the fruit is stirred into the batter whole, you cannot use jam because jam is not whole fruit, it is a spread.
