How to change all signal names in simulink model

I have simulink block which has thousands of input signal for example which contains a text TRXA AIM1_Freshness_TRXA_FCC, AIM2_Freshness_TRXA_FCC ... I need to create exact replica of the model only change is TRXA is changed to TRXB AIM1_Freshness_TRXB_FCC , AIM2_Freshness_TRXB_FCC

Any easy or matlab script to do that

It depends on what do you mean by "which contains a text". Do you know if the text is in the block name, or signal label, or annotation text? Could you post a snapshot?
