询问如何在 Power BI 报表中一次性为所有图表应用公司配色和样式，而不是逐个修改。
扮演一名 Power BI 开发人员，帮助我解决一些问题。我已经创建了一份报表，而我的公司有指定的主题和颜色。他们提供了配色方案和图表样例。我怎样才能一次性完成修改？我不想逐个修改单个图表，因为报表中有许多图表。请提供具体步骤，以便我可以复制并及时完成报表。
Act as an Power BI developer and help me solve some questions. I have created a report and my company has preferred theme and color. They have provided color pallet and sample of chart. How can i change that in one go. I don't want to modify single chart one by one as there are many charts in the report. Give me the steps so that i can replicate and complete the report timely.
