When dasa kusala are done without at least basic understanding of buddh dhamma, i.e. Paṭicca Samuppāda + four noble truths + tilakkhana, they are just puñña abhisankhara.
When done with understanding of dhamma they are just kusāla saṅkhāra not kusāla abhisaṅkhāra.
There is no such thing as kusāla abhisaṅkhāra. Abhisaṅkhāra either puñña or Apuñña, are done out of ignorance.
With understanding of dhamma to minimum threshold of sottapana anugami, slowly kusāla mula Paṭicca Samuppāda is cultivated, leading one to nibbanā through removal/reduction of tanha (attachment either through hate/greed/ignorance). This cycle is initiated with kusāla mula saṅkhāra,they are special kind of saṅkhāra.
