Easily find all combinations that equal a given sum in Excel

Supposing, there is a list of numbers (whole numbers, decimal numbers or negative numbers), and now, you want to find all possible combinations from these numbers that equal a given sum. Normally you can use formulas, Solver Add-in or User-defined function to achieve it, but it is time-consuming and not easy to handle. Here with the useful Make Up a Number utility of Kutools for Excel, finding all combinations that equal a given sum has never been so easy in Excel.

È possibile escludere delle combinazioni da quelle trovate ?

instead of "processing, please wait" it needs to have a counter which displays either how much time is estimated to be remaining to calculate or an actual counter of the calculations done and remaining to be counted. ie i have waited over 4 hours for the program to work out my 44C8 query (177m combinations) but i don't know whether the program has crashed or is still calculating.

Still going after another 6 hours (10hrs all up). i assume it has crashed and will force close the program.

ok just tried a 35C8 and it took just over 90mins, so maybe 44C8 takes 11.5hrs.
