Hello! I need to add a custom button to the Address on the Leads screen. The address section is a common screen

This is my goal (shown in classic UI)

Even if I could extend/modify the “common” files, I don’t want to add this button to every place that this address is used. The other issue is that the Address section is part of tabGeneral which includes the Contact section.
<qp-tabbar id="LeadCurrent_tab" class="label-size-m" wg-container="">
<qp-tab id="tabGeneral" caption="General" ref="tabGeneral_Content"></qp-tab>
I am lost as to how I can accomplish this.
Would I have to completely replace the tabGeneral with a custom tab and put all the fields and related business logic?
Thanks in advance for any tips.
