Yes, please send me your code, in a way that is compatible with the current implementation of PLV:
https://github.com/brainstorm-tools/brainstorm3/blob/master/toolbox/connectivity/bst_connectivity.m#L505
Ideally, you should be able to replace the case 'plv' with your code and it should work.
I will add your code to a new case ciplv and add everything else needed in the rest of the software so that the output files are recognized correctly everywhere.
Thanks!
