How to create custom matrix structure with dynamic headers from measures

Hi,

I am looking for custom matix structure with dynamic headers coming from created measures.

my existing structure look like below.

Prodcut service  total %total open Open% Close close%
Phase 5               2     13%      5         100%    0        0%
Phase 4               0      0%       5         100%   0        0%
Phase 3               5      33%     0           0%     3        100%
Phase 2               3      20%    1           50%    1        50%
Phase 1               5      33%     0           0%     0         0%
Total                  15     100%   1           13%    4         26%

In the above all column headers are done from measures and iwould like to create new header for goruping 2 columns as one set for example

for measures total and %total  i need to create new header "TOTAL" with merge and style .

for measures Open and %open i need to create new header "Open" with merge and style .

for measures close and %close i need to create new header "Close" with merge and style .

my overall expected output like below
