Remove one band from for BSE kernel and dielectric constant calculation

Dear Yambo team,
Is there anyway i can remove one band from the summation of calculation (Both BSE and
for example for BSE kernel, i have
% BSEBands
100 | 180 | # [BSK] Bands range
%n
then i find out an unrealistic band 148, and want to remove the contribution of this specific band.
For BSE kernel building since it is a matrix of Nv*Nc*Nbz size. What i mean remove would be setting all the c=148 matrix element to be zero.
For Dielectric matrix part it would be removing one term in the summation of band.
