Esaal-e-Sawaab

Reciting a para for one's own khatam and sending it as esaal-e-sawaab for another khatam

Q: I would like to find out regarding Quraan Khatams.

Usually when someone passes away and one goes to visit the relatives of the deceased - there are paras left out for whoever chooses to read and send esaale sawaab for the deceased. Similarly a group of willing relatives/ friends may distribute paras amongst themselves in order to complete a khatam for the deceased person.

So usually in the above cases, one chooses whichever para one likes - to contribute to the khatam. 

My question is: if one reads Quraan tilaawah daily and makes a khatam of that over the course of a month or a few months and perhaps, for example they are currently on the 10th para. So will it be permissible/valid for them to also choose the 10th Para for their khatam for the deceased person with the intention of only reading the para ONCE and the intention being for ones daily tilaawah as well as - contributing to the khatam for the esaale sawaab for the deceased person?

Esaal-e-thawaab

Q: I have a question regarding esaal-e-thawab. When we do a normal act but for the sake of Allah we get rewarded. For example, if we eat with the intention of being able to fast the next day, then we are rewarded for this intention even though eating is not an 'ibaadah in itself.

My question is: can we donate this kind of reward to the deceased (even though it does not come from a direct form of 'ibaadah) or is it only reward from direct types of worship (praying, fasting, etc.) that can be rewarded?
