How to use the same clicked.connect function for multiple buttons? - sqlite

Question

I am working on a GUI in pyqt5, that using a database (sqlite3). First, I'm uploading the entire data into a QTableWidget. Then, depending on the user filter parameters (2 comboboxes and 2 free text lineEdits which are signaled by 1 button), the filtering function is called and the data is filtered. The user may do another filter afterwards, and the table will be filtered again according to the new request.
The filter function is called upon one of three conditions:
The first combobox text changed ("comboType")
The second combobox text changed ("comboMaterial")
The button "Filter Ac/AL" clicked ("pbFilter ALAc")
The question: the filtering is always initializes when the "comboType" text is changed only (since it's the first signal). When the user wants to filter according to the second or third conditions, the function can not be called and the filtering can not be conducted. The script is stuck until the first condition will occur (call the comboType.currentTextChanged.connect).
Is there any way to "jump" to the second or third condition when clicked?
