Methods and systems for combinable conference rooms. The method including establishing a baseline audio and video (AV) signal flow for combinable rooms in a baseline state, generating a baseline macroinstruction for the baseline state, establishing non-baseline AV signal flows for one or more non-baseline states, where each non-baseline AV signal flow turns off certain paths in the baseline AV signal flow to establish AV signal flow isolation between certain of the combinable conference rooms, generating a non-baseline macroinstruction for each of the one or more non-baseline states, providing an interface for selecting the baseline and each non-baseline macroinstruction, where the baseline and each non-baseline macroinstructions are generated for operation with an AV controller and the interface which collectively control AV signal flow of the combinable conference rooms, and configuring the combinable conference rooms based on selection, via the interface, of one of the baseline or the non-baseline macroinstructions.
