i have had to design insert locations before and had to write my own spreadsheet (i don't know of an available program but there may be one). normally the insert locations are designed by dayton or burke which have their own software that you probably won't be able to get. here is more on it:
is there a special formula for creating your tabulation with the spreadsheet?
there was a book we had that gave guidance to placing the inserts. we figured the lifting of the panels so that the stresses would be well under that required to crack the panel along with some of the generic guidance the book provided, the rest is just statics. it is kind of a difficult spreadsheeet to set up the first time especially if you have panels with a lot of openings or more than one story. be careful, tilt panel lifting can be dangerous if the inserts are not properly designed.
we make a living by what we get, we make a life by what we give.

do you have the pci design manual?
it is expensive but it is very useful in its approach to many differing precast applications.
many precast lifting configurations are based on simple spans and assumed uniform moments.
depending on panel capacity, you may require a lifting beam if the panel cannot sufficienty distribute the loads applied for lifting.
again, buy the manual. talk to professionals in your area. ensure you can call yourself competent with regard to osha requirements for rigging such a load.
