The name of each structure must be unique. * In the [structure details](https://help.qomeet.com/en/article/structure-details-16vfkxa/), you will be able to access its list of participants and configure its settings. * To create structures in bulk from an existing file, you can use the [structure import](#3-import-structures-from-an-excel-file) feature. ### List of structures * Click on the **Add/Remove Columns** icon to choose which information you wish to display or not.

This will prevent structures from registering new participants. ![](https://storage.crisp.chat/users/helpdesk/website/-/c/d/0/9/cd093f68934ed800/image_1d9i5g9.png =1175xauto) You can also modify the services authorized for several structures at once, using the [grouped update](#3-grouped-updates) feature. ![](https://storage.crisp.chat/users/helpdesk/website/-/c/d/0/9/cd093f68934ed800/image_151aas6.png =716xauto) ### Import structures from an excel file The **Import** button at the top of the page allows you to create structures in bulk: download the template file, fill it in, then select the file to import your list of structures. || Please be sure to spell the names of your participant categories correctly.
